I love the new picture you drew! Funny and even has pancakes. I can't complain about something if there are pancakes in it.
There are organizations dedicated to tracking NEOs (near earth objects) but yeah, the real truth is if something hits us, there isn't much we can do about it. On Star Trek they used 'repulsor beams' once, if I recall, to move aside an asteroid from hitting a planet. And then of course we have our movies from the 90s like Armageddon and Deep Impact that offer far-fetched solutions to the issue.
Maybe we can train an heroic team of valiant budgies to fly to space with a net and drag the NEO away? It could be a fun kid's movie, after all.
But in all honesty, if something hits chances are good we are wiped out. It won't take a very big object to permanently eliminate most of the current life on earth. Earth will adapt and life will go on, but it won't look anything like it does now. And we probably won't get to see it.
In the face of this I am not going to worry about it, as Janimal wisely suggested.
